Pre-treatment of timber in a controlled factory environment.
Timber Treatment Application Technologies
Whether with a flame retardant or preservative product, factory application ensures a measured improvement in performance with the minimum of environmental impact or human exposure. WPA Member suppliers
There are three proven and widely available industrial timber treatment processes:
Wood Modification
Vacuum Pressure Impregnation
A penetrating process used for both flame retardant and preservative treatment application to solid timber and wood based products.
Integral to Manufacture
WPA approved flame retardants can be incorporated to particle board and medium density fibreboard (MDF) as an integral part of production (achieving the performance set out in relevant fire test Classification Report).
PROCESSES ARE SPECIFIC TO MANUFACTURER.
Factory applied Coatings
WPA approved flame retardants can be surface applied in a factory under third party quality assured processes (achieving the performance set out in relevant fire test Classification Report).
PROCESSES ARE SPECIFIC TO MANUFACTURER.
Timber Treatment Plant Control Systems
Most treatment formulations are supplied as concentrate which need to be added to either water or another liquid to create a 'solution'. The way they are mixed depends on the formulation, timber species, component and treatment class required. Specific solution loading guides published by the formulation manufacturers and used by plant operators should be quality checked on a regular basis.
Plant control software systems significantly enhance quality control and data reporting around the treatment operation. Such systems can be obtained from formulation manufacturers or plant suppliers.
Timber Treatment Incising Technologies
Incising technologies are increasingly utilised for preservative impregnation of high risk post components - small even incisions provide channels for deeper penetration of the preservative formulation.
Specialised systems for use either as stand alone or as part of the whole production line can be designed and engineered to suit a sawmill's particular set-up. There are machines to incise either round or flat sided posts.
